TIME APPARATUS FOR USE WITH SUBMARINE MINES.

Application filed April 25,

To all whom it may concern Be it known that I, JEAN REY, a citizen ofthe Republic of France, and a resident of Paris, France, engineer, haveinvented a new and useful Improvement in Time Apparatus for Use withSubmarine Mines, which invention is fully set forth in the followingspecification.

This invention relates to improved time apparatus for those submarinemines which when released by the submarine boat carrying them falltogether with their anchor to the bottom of the sea.

The time apparatus in accordance with this invention has for its objectto liberate the mine from its anchor at the moment re quired and toallow its mooring rope to unwind, the time apparatus is automaticallyreleased directly the mine leaves the submarine by the movement of acock or a bolt, the breaking of a member or in any other known way.

Three methods of carrying out the invention are illustrated in theaccompanying diagrammatic drawing in'cases where the mine is fixed tothe side of the submarine boat.

In Figure 1, the control is effected by the gid of a projection fixed tothe submarine oat.

In Fig. 2 the control is efl'ected by the aid of a cock.

In Fig. 3, the release is effected by the breakage of an immobilizingmember.

Figs. 4, 5 and 6 are diagrammatic views showing other constructionalforms of means for releasing the timing device.

Fig. 1 shows the mine a on its anchor b.-

the attaching arrangement is illustrated diagrammatically in the form ofhooks 0. The assembled mine and anchor are retained near to thesubmarine boat by any known means not illustrated. A time apparatusillustrated diagrammatically in the form of a dash-pot e the piston ofwhich is forced to the right by a spring 7 is maintained stationary by aprojection 9 carried by the submarine boat.

The time apparatus 6 becomes separated from the projection 9 when, atthe moment of launching, the mine is detached from the submarine boat tofall to the bottom of the sea; it is now free to move. After a certaininterval dependent on construction the hooks c are moved the extentnecessary to free the mine from its anchor 12.

Specification of Letters Patent.

Patented Nov. 9, 1920. 1918. Serial No. 230,849.

In Fig. 2 the opening of a cook it brings into action the time apparatus6 A project1on 9 carried by the submarine boat, knocks the tail of thecook it and opens it when, on launching, the mine becomes detached fromthe submarine boat to fall to the bottom of the sea.

In order better to regulate the path of travel ofthe cock it near to theprojection 9 a guide 2' may be provided to guide the mine with referenceto the submarine boat.

The cock h when open allows the time apparatus 6 to operate. After acertain interval it actuates the hooks c as in Fig. 1.

f course, in place of actuating a cock, the rojection may lift a pin kas shown in 1g. 4; or operate a bolt 2', through an immobilizing arm asin Fig. '5; or break an immobilizing member a at m as in Fig.

6, or cause any other operation which brings into action a timeapparatus of any type even other than those illustrated.

In Fig. 3 the projection is replaced by a fixed point 7a which bringsinto action the time apparatus 6 through the intermediary of a cable Zwhen, on launching, the minebecomes detached from the submarine to fallto the bottom of the sea.

The pull of the cable Z causes the immobilizing member 97. to break atm. The time apparatus 6, a certain time after being thus liberated,actuates the hooks 0 as described for Fig. 1.

When the mine has been thus liberated, it rises to a certain level belowthe sea surface and is then arrested by known mechanism andmaintainediat the degree of immersion desired.

Claims 1. In a combination, a submarine mine provided with a separableanchor having a mooring rope-connection with said mine and adapted to besupported from the side of' a boat, releasable connections between themine and anchor, sprlng-pressed means normally tendlng to move sa1dconnectlons 1nto releasing position and timing means set into operationby launching the mine for delaying the operation of said spring-pressedrelease operating means to delay release of the mine from its anchor.

2. In combination, a submarine mine pro vided with a detachable anchorhaving a mooring-rope connection with said mine and adapted to besupported from the side of a submarine boat, releasable catch meansnormally connecting said mine and anchor, to release the mine and anchorand to permit a spring-pressed catch releasing rod northe mooring ropeto unwind.
